I have upgraded to Xcode 13, I'm now getting the error "Tab Bar Appearances before ios 13". When I click on the error it leads me to a tab bar in a Storyboard without providing additional information.

What could be causing this error?

Did you copy this file from an older version of Xcode and attempt to run it on Xcode 13? If so, I believe this message is telling you that the Tab Bar is outdated for anything before IOS 13. You will need to rework that piece of code, creating a new Tab Bar.

If not, I would attempt to run the simulator and when it crashes, check the Debug Area and it should give you a little more information.
